25
what did neuroscientists say the cause of GAD was?
- malfunctioning GABA feedback system - malfunctioning emotional brain circuit
26
what is social anxiety disorder?
fear of talking in public, embarrassment and functioning poorly in front of others
27
what did cognitive-behavioural theorists say the cause of social anxiety disorder was?
- unrealistically high social standards - view oneself as socially unattractive and unskilled
28
what is phobias?
- strong, irrational fears of objects or situations and the desire to avoid the object of the phobia - do not usually go away on their own, intensify over time
29
what are the explanations behind phobias?
- classically conditioned fear - avoidance behaviours are reinforced through operant conditioning - modelling of fearful behaviour
30
what is panic disorder?
- anxiety response occurs suddenly, unpredictable and is very intense - person lives in fear of the next attack and changes their behaviour to avoid panic attacks
31
what are the explanations behind panic disorder?
- malfunctioning brain circuit and excess norepinephrine - misinterpretation of bodily sensations
32
what is obsessive compulsive disorder?
individuals have unwanted repetitive thoughts and tend to engage in repetitive behaviours
33
what does obsessive and compulsive mean?
Obsessions = cognitive component (repetitive and unwanted thoughts) Compulsions = behavioural component (repetitive response to attempt to ease anxiety)
34
what did cognitive-behavioural theorists say about OCD?
Learning that compulsive behaviour relieves distress
35
what did neuroscientists say about OCD?
- low serotonin activity - cingulate cortex and hypothalamus active the OCD impulses - amygdala drives the fear and anxiety components of the OCD response
36
what is post traumatic stress disorder?
- persistent depression and anxiety after a traumatic event - lasts more than a month, may begin shortly or years after the event
37
what are the explanations of PTSD?
- damaged hippocampus, amygdala and increased cortisol and norepinephrine - perceive negative events as beyond their control - negative childhood experiences:
38
what is schizophrenia?
a “split mind” characterized by disordered thought, lack of contact with reality, hallucinations
39
what are the symptoms of schizophrenia?
Hallucinations = alterations in perception Delusions = beliefs that are not based on reality Disorganized behaviour = ‘all over the place’ to the extent that completing a task is difficult
40
what are the 4 categories of symptoms of schizophrenia?
positive, negative, cognitive, psychomotor
41
what are positive symptoms of schizophrenia?
presence of problem behaviours; → delusions, disorganized thinking and speech, hallucinations
42
what are negative symptoms of schizophrenia?
absence of healthy behaviors; pathological deficits in behaviour → lack of speech, flat affect, loss of volition, social withdrawal
43
what are cognitive symptoms of schizophrenia?
impairment in cognitive functions → problems with memory, executive function, intelligence
44
what are psychomotor symptoms of schizophrenia?
abnormal movements → awkward movements, odd gestures, catatonia
45
what is the onset and development of schizophrenia?
- typically end of adolescence and in early childhood, later for women than men - roughly 1 in 100 people, equal men and women
46
what are the explanations of schizophrenia?
Genetics Abnormal brain structures - smaller temporal lobes and frontal lobes - structural abnormalities of hippocampus, amygdala and thalamus - cerebral ventricles are 20-30% larger in size Biochemical abnormalities - too many dopamine receptors help to explain paranoid and hallucinations - abnormal glutamate and serotonin activity may play a role
47
what are the 5 types of somatic symptom and related disorders?
somatic symptom disorders, illness anxiety disorder, conversion disorder, psychological factors affecting other medical conditions, factitious disorders
48
what are the explanations for somatic symptom and related disorders?
behaviourists: classical conditioning of fears, modeling cognitive theorists: misinterpret/ very sensitive to bodily cues socio cultural theorists: many non-western cultures transform personal distress into somatic complaints/ symptoms
49
what is somatic symptom disorder?
- one or more somatic symptoms that cause distress and significant disruption to daily life - concern has lasted over 6 months
50
what is illness anxiety disorder?
- individual is preoccupied with having a serious disease despite minimal or no somatic symptoms - excessive care seeking for over 6 months
51
what is conversion disorder?
- the development of sudden symptoms suggestive of neurological damage yet perfectly healthy (blindness, paralysis, seizures, loss of feeling) - individual is concerned with their symptoms
52
what is psychological factors affecting other medical conditions?
when psychological factors adversely affects or worsens a current medical condition
53
what is factitious disorder?
when an individual purposely assumes physical or psychological symptoms in order to adopt the patient role
54
what is dissociation?
refers to a separation of conscious awareness from thoughts, memory, bodily sensations, feelings or even from identity
55
what is a dissociative disorder?
refers to dysfunction and distress caused by a chronic and severe dissociation
56
what are the explanations of dissociative disorders?
psychoanalytic perspective = repression cognitive perspective = coping with abuse learning perspective = dissociation pays social influence = therapists encourage biological approach = smaller hippocampus and amygdala
57
what are the 3 types of dissociative disorders?
dissociative amnesia, depersonalization disorder, dissociative identity disorders (DID)
58
what is dissociative amnesia?
loss of memory with no known physical cause; inability to recall memories
59
what is depersonalization disorder?
a strong feeling of disconnection from one’s regular identity and awareness; usually triggered by stress
60
what is dissociative identity disorder (DID)?
- development of multiple personalities (aka multiple personality disorder) - each identity is unique, may or may not know about each other, not in conscious at the same time
61
what personality disorders fell into dramatic and impulsive behaviours?
antisocial, borderline, histrionic, narcissistic
62
what personality disorders fall into anxiety and fearfulness behaviours?
avoidant, depended, obsessive-compulsive
63
what personality disorders fall into odd and eccentric behaviours?
paranoid, schizoid, schizotypal
64
what is antisocial personality disorder?
- lack a conscience and empathy - failed to respond to punishment - disregard for others rights or preferences - may be charming and manipulative
65
what did the behaviourist theorists say about anti-social personality disorder?
modelling = parents have antisocial personalities operant conditioning = parent reward the wrong behaviour
66
what are the biological factors related to anti-social disorders?
lower serotonin, deficient functioning of the frontal lobes, less anxiety
67
what is borderline personality disorder?
- intense extremes between positive and negative emotions - unstable sense of self - impulsivity and volatility - difficult with social relationships
68
what does the bisocial theory say about borderline personality disorder?
child has difficulty identifying and controlling emotions, emotions are punished and disregarded
69
learned helplessness
a state that occurs after a person has experienced a stressful situation repeatedly
70
attribution helplessness theory
individuals come to feel helpless through learning to attribute internal, stable, and global causes to a variety of events.
71
cognitive triad
a set of three negative beliefs about the self, the world, and the future
72
magnification
an individual will perceive a relatively minor incident as being much more important
